Description
Technical Field
[0001] This utility model relates to the field of wire testing tooling technology, and more specifically to an antenna rotation testing device. Background Technology
[0002] In fields such as communications, radar, and satellites, antennas are the core components for signal reception and transmission, and their performance directly determines the communication quality, detection accuracy, and signal coverage of the equipment. To ensure that antennas can adapt to different azimuth and elevation angles in practical applications, it is necessary to use a rotation testing device to simulate multi-attitude conditions and comprehensively test key parameters such as signal gain, directivity, and impedance matching of the antenna. Therefore, the antenna rotation testing device has become a core piece of equipment in antenna research and development, production, and quality inspection.
[0003] However, existing antenna rotation testing devices still have shortcomings: for example, existing devices can only achieve single-dimensional adjustment of the antenna's horizontal or vertical rotation, and cannot simultaneously meet the multi-attitude testing requirements in three-dimensional space. This results in the inability to simulate the combined working conditions of horizontal scanning and vertical pitch of the antenna in actual use. It is necessary to disassemble and adjust the antenna installation attitude multiple times to complete the full parameter test, which is not only cumbersome to operate, but also prone to affecting the test accuracy due to disassembly and assembly errors. Utility Model Content
[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides an antenna rotation testing device to solve the problem that traditional devices in the background art are difficult to simulate antenna testing at multiple angles.
[0005] This utility model provides the following technical solution: An antenna rotation testing device includes a rotating base, a vertical rotating disk fixedly installed at the output end of the rotating base, and a test antenna fixedly installed at the output end of the vertical rotating disk via two connecting plates; the vertical rotating disk includes upright plates, two upright plates fixedly installed at the output end of the rotating base, and the inner sides of the two upright plates fixedly installed via several connecting rods; the inner sides of the two upright plates are provided with a swing mechanism, a semi-circular guide rail, and a driving mechanism; a semi-circular movable frame is installed at the output end of the swing mechanism, the semi-circular movable frame is connected to the semi-circular guide rail, the swing mechanism and the semi-circular guide rail are used to position the center of the semi-circular movable frame, the output end of the driving mechanism is connected to the semi-circular movable frame, and the output of the driving mechanism is used to drive the semi-circular movable frame to rotate around the center; the two connecting plates are fixedly installed on the side wall of the semi-circular movable frame.
[0006] Furthermore, the swing mechanism includes a central shaft, which is rotatably sleeved on the inner side of the two upright plates. Two rocker arms are fixedly installed on the side wall of the central shaft, and the other ends of the two rocker arms are connected to a semi-circular movable frame. The central axis of the central shaft overlaps with the center of the semi-circular movable frame.
[0007] Furthermore, the semi-circular movable frame includes two semi-circular movable arms, one end of which is fixedly connected by a connecting rod two, and the other end is connected to the swing mechanism; the semi-circular guide rail frame includes two semi-circular fixed arms, the inner sides of which are fixedly connected by several connecting rods three, one end of which is connected to the inner sides of the two upright plates by a connecting rod four, and the other end of which is connected to the drive mechanism; both semi-circular fixed arms have arc-shaped through slots on their side walls, the center of which overlaps with the center of the semi-circular movable arm, and the connecting rod two passes through the arc-shaped through slots.
[0008] Furthermore, the driving mechanism includes a rotating shaft and a motor. The rotating shaft is rotatably sleeved on the inner side of the two upright plates. The motor is fixedly installed on the outer wall of the upright plates through a fixing plate. The output end of the motor is connected to one end of the rotating shaft through a gear meshing group. Two gears are fixedly connected to the side wall of the rotating shaft.
[0009] Furthermore, the rotating base includes a base plate, and a support platform is connected to the top of the base plate by several columns. A rotating seat is provided on the top of the support platform, and a gear disk is fixedly installed on the top of the rotating seat.

[0010] The technical effects and advantages of this utility model are as follows:
[0011] This invention achieves omnidirectional angle adjustment through a vertical rotating disk and connecting plate in conjunction with a driving antenna. The dual systems drive independently and work together, simulating the combined horizontal scanning and vertical pitch conditions of the antenna in practical applications. It can complete full-parameter testing without multiple disassembly and adjustment of the antenna attitude, greatly improving testing efficiency. At the same time, it avoids interference from disassembly and assembly errors on the test results, ensuring that the test data can truly reflect the antenna's performance under multiple attitudes, such as signal gain and directivity.

[0018] The specific embodiments of this utility model will now be described in detail with reference to the accompanying drawings.
[0019] This utility model provides an antenna rotation testing device, including a rotating base 1. A vertical rotating disk 2 is fixedly installed at the output end of the rotating base 1. A test antenna 4 is fixedly installed at the output end of the vertical rotating disk 2 through two connecting plates 3. The vertical rotating disk 2 includes two upright plates 21. The two upright plates 21 are fixedly installed at the output end of the rotating base 1. The inner sides of the two upright plates 21 are fixedly installed through several connecting rods 22. The inner sides of the two upright plates 21 are provided with a swing mechanism 23, a semi-circular guide rail frame 25, and a driving mechanism 26. A semi-circular movable frame 24 is installed at the output end of the swing mechanism 23. The semi-circular movable frame 24 is connected to the semi-circular guide rail frame 25. The swing mechanism 23 and the semi-circular guide rail frame 25 are used to position the center of the semi-circular movable frame 24. The output end of the driving mechanism 26 is connected to the semi-circular movable frame 24. The output of the driving mechanism 26 is used to drive the semi-circular movable frame 24 to rotate around the center. The two connecting plates 3 are fixedly installed on the side wall of the semi-circular movable frame 24.
[0020] In use, the test antenna 4 is fixed on the two connecting plates 3. The output of the rotating base 1 drives the vertical rotating disk 2 to rotate horizontally, so that the test antenna 4 can be adjusted in the horizontal direction. The operation of the vertical rotating disk 2, i.e., the output of the drive mechanism 26, drives the semi-circular movable frame 24 to rotate around the center point, so that the test antenna 4 can be adjusted in the vertical direction. By combining horizontal and vertical rotation, the test antenna 4 can achieve the effect of multi-directional angle adjustment, realizing the antenna multi-directional testing requirements.
[0021] Furthermore, the rocking mechanism 23 includes a central shaft 231, which is rotatably sleeved on the inner side of the two upright plates 21. Two rocker arms 232 are fixedly installed on the side wall of the central shaft 231, and the other end of the two rocker arms 232 is connected to the semi-circular movable frame 24. The central axis of the central shaft 231 overlaps with the center of the semi-circular movable frame 24.
[0022] The structure of the swing mechanism 23 can position the center of the semicircular movable frame 24, thus preventing the center of the semicircular movable frame 24 from shifting during its rotation.
[0023] Furthermore, the semi-circular movable frame 24 includes two semi-circular movable arms 241, one end of which is fixedly connected by a connecting rod 242, and the other end is connected to the swing mechanism 23; the semi-circular guide rail frame 25 includes two semi-circular fixed arms 251, the inner sides of which are fixedly connected by several connecting rods 252, one end of which is connected to the inner sides of two upright plates 21 by a connecting rod 253, and the other end of which is connected to the drive mechanism 26. The sidewalls of the two semi-circular fixed arms 251 are provided with arc-shaped through slots 254, the center of which overlaps with the center of the semi-circular movable arm 241, and the connecting rod 242 passes through the arc-shaped through slots 254.
[0024] The structure fixes the position of the semicircular fixed arm 251 through the connecting rod 253 and the drive mechanism 26. The drive mechanism 26 drives the semicircular movable arm 241 to rotate around the center point. Through the positional relationship between the connecting rod 242 and the arc-shaped through slot 254, the center of the semicircular movable arm 241 can be located, and the rotation angle of the semicircular movable arm 241 can be limited to avoid the test antenna 4 from colliding with other components due to the excessive rotation angle of the semicircular movable arm 241.
[0025] Furthermore, the drive mechanism 26 includes a rotating shaft 261 and a motor 263. The rotating shaft 261 is rotatably sleeved on the inner side of the two upright plates 21. The motor 263 is fixedly installed on the outer wall of the upright plate 21 through a fixing plate 264. The output end of the motor 263 is connected to one end of the rotating shaft 261 through a gear meshing group 265. Two gears 262 are fixedly connected to the side wall of the rotating shaft 261.
[0026] Both semicircular movable arms 241 have several toothed grooves on their side walls. Two gears 262 mesh with the toothed grooves on the side walls of the two semicircular movable arms 241 respectively. The motor 263 outputs power to drive the rotating shaft 261 to rotate, and the rotating shaft 261 drives the two gears 262 to rotate. Under the meshing action of the gears 262 and the toothed grooves on the side walls of the semicircular movable arms 241, the semicircular movable arms 241 can be driven to rotate.
[0027] Furthermore, the rotating base 1 includes a base plate 11, and a support platform 12 is connected to the top of the base plate 11 by several columns. A rotating seat 13 is provided on the top of the support platform 12. A gear disk 14 is fixedly installed on the top of the rotating seat 13. A second motor 15 is fixedly installed on the bottom of the support platform 12. The output end of the second motor 15 passes through the support platform 12 and is connected to a second gear 16. The second gear 16 meshes with the gear disk 14. The second motor 15 outputs power to rotate the second gear 16. A vertical rotating disk 2 is fixedly installed on the top of the gear disk 14.
[0028] The rotation of gear disk 14 can be achieved through the meshing relationship between gear disk 14 and gear 16, thereby causing the vertical rotating disk 2 to rotate as a whole.
[0029] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. This utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
